Pre-Debit Notification API

The Pre-Debit Notification API allows the merchants to send a pre-debit notification to the customer regarding an upcoming payment which will be deducted from the customer’s account as part of the registration. There is a mandate to send this notification to the customer at least 48 hours before the actual debit, that is, 48 hours before calling the Recurring API.



  • Unless the Pre-Debit notification interface is implemented, the Recurring API will not work, and you will not be able to charge the customer for the given billing cycle.
  • Pre-Debit notification is necessary only for Cards and UPI and works for only these two payment modes
